GB/T902.2 RD Type Threaded Studs for Drawn Arc Stud Welding with Ceramic Ferrule

Description

The GB/T902.2 (RD) Threaded Studs are specialized fasteners used in drawn arc stud welding processes, commonly paired with ceramic ferrules for optimal heat retention and shielding during welding. These studs are fully or partially threaded and offer superior holding power and structural strength.

Manufactured from high-grade carbon steel or stainless steel, they are engineered for robust welding performance across a wide range of industrial applications, including steel construction, shipbuilding, machinery manufacturing, and bridge erection.

A variety of finishes are available including plain, black oxide, zinc electroplating, hot dip galvanizing, dacromet, copper plating, nickel plating, and zinc impregnation, offering corrosion resistance and application-specific benefits.

OEM customization is available according to customer drawings or physical samples, and free samples are provided for testing and evaluation.
